on the new comp, if not already there, make a Program Files (x86) folder at the location where it is on the old comp. drive for 'Documents/Arma3', 'Program Files (x86)/Steam', 'SteamLibrary'ħ. make your external drive ready - you'll need enough space depending on how many games you have installed, maybe check your Steam installation and SteamLibrary folder for size first.Ħ.

I assume your Arma 3 installation is located in it's own 'SteamLibrary' folder on a different drive, if not just skip these steps with the copying the 'Steamlibrary'ĥ. if your 'Documents' folder on the new machine is at a different (costum) location than on the old, please change it (on the new comp) to the structure from the old comp (right click 'Documents' change path/location)ģ. if your Steam install 'Program Files (x86)s' folder at new machine is at a different (costum) location than on the old, please change it to the structure from the old compĤ. Don't install Steam yet on the new machine (if you already did, deinstall Steam and delete all 'SteamLibrary' and installed games)Ģ.

It maybe looks complicated but it isn't.ġ. We going to kind of 'mirroring' our Steam installation with all installed games and workshop content. This is how I managed to transfer my Steam (all games) + Arma 3 installation + all mods and DLC without need to download anything on the new machine.

Steam re download workshop content
